the pcuk nurse i talked to seemed to indicate there is no scientific consensus on reasons behind fluctuating psa, i cant find any research on line..i think chris may be correct in his conclusion
.on the one hand the lowering of psa ,as peter says ,is a positive as it may indicate delay of any required treatment,but doubt in the process never good (why measure so sensitively if measurements can vary due to outside factors) and as trend over 12 months still upward,and as lyn says psa still too high for a prostate less man,i have to place trust in oncology..be interesting if they have different emphasis to urologist.,though as my psa now below 0.2,im now below treatment threshold on tyneside.
..as for my breakfast im a granola grandad,well thats what my grandaughter calls me.thank you,gan canny,joe
